When in your passion for doing something you have to put money into it to pay someone to do it for you, it doesn't become so much of a passion.
This is not true at all. By putting your money in your own project you invest your finances into your passion as well.
Example: I'm drawing a comic, I can't do it alone, because quality comic requires a lot of effort and I need to be able to upkeep the speed of the release, thus I hire a few people to deal with a few steps in the pipeline for me. Yes, I have to pay them to do it, but it doesn't diminish my interest in my project and it doesn't change my attitude towards the work we've been doing. By hiring a few more people we speed the execution up, we have more results, we get to see the story unravel faster and it keeps bringing more people into the project. I get to see people's reaction, people's investment and that only inspires more to invest even further into the project. It's all connected and paying people to do some of your job doesn't diminish the passion behind the development.
Does it make development more complex? Yes. Does it make it more mundane? Naturally, because any work requires it to be speedy and it becomes more of a job than a hobby - it's a natural process for anything that has a bigger scope. Can it cause a creative burn out? It can, but it works in both cases. And in case of working alone you are endangered to have a burn out way more than if you have a team, not only because you share your physical burdens with them, but also because a collective that aims to achieve a common goal inspires you to keep going and even to do more, so in fact it's a big boost of moral.
Naturally there's a point where indie becomes corporate and that's where fun stops, where passion dies and becomes a tedious struggle, but it's usually caused by way bigger teams that require to have a publisher who dictate their terms in order to meet certain criteria on the market, which causes limitations. But you need to get to that point and it's not that easy and not everyone does that nor aims to get there in the first place.
As long as your project is yours, as long you are free to execute all of your creativity and voice your ideas in the media of your choice, as long as you don't work off your buttocks to the point where you have health issues, as long as you still have genuine things to say to your community, your project will remain your passion, regardles of the fact that you might have to pay other people to help you out. Not only that, but having other people on board might even cause a positive effect on your working process and on your motivation, because you know that you're being supported and people care.
